Damien Miller6e1057c2002-01-22 23:05:59 +1100[diff] [blame]59When run without arguments, it adds the files

Damien Miller450a7a12000-03-26 13:04:51 +1000[diff] [blame]64Alternative file names can be given on the command line.
65If any file requires a passphrase,
Damien Miller32aa1441999-10-29 09:15:49 +1000[diff] [blame]66.Nm
Damien Miller22c77262000-04-13 12:26:34 +1000[diff] [blame]67asks for the passphrase from the user.
Ben Lindstromaafff9c2001-05-06 03:01:02 +0000[diff] [blame]68The passphrase is read from the user's tty.
Ben Lindstrom12de6162001-04-10 02:46:54 +0000[diff] [blame]69.Nm
70retries the last passphrase if multiple identity files are given.
Damien Miller32aa1441999-10-29 09:15:49 +1000[diff] [blame]71.Pp
72The authentication agent must be running and must be an ancestor of

Damien Miller32aa1441999-10-29 09:15:49 +1000[diff] [blame]83.It Fl d
84Instead of adding the identity, removes the identity from the agent.

86Deletes all identities from the agent.
Ben Lindstrom2f717042002-06-06 21:52:03 +0000[diff] [blame]87.It Fl x
